Erm, are you you talking about the Charleston rally in which a Neonazi ran over counter protestors? And if yes,are you saying it's a bad thing less people showed up to sing "Jews will not replace us" the year after?

And regarding the symbolism...I can kinda see that example, maybe, but I generally don't see the hammer and sickle used in mainstream politics either. And even then, there is a line between something like the hammer and sickle which was used before and after Lenin/Stalin as a symbol vs. the swastika which was literally designed by Nazis and only ever used by them (the Buddhist one is slightly different)

If anyone directly sympathises with Stalin/Lenin and calling for dekulakhisation, I'd expect that to also remove them from polite conversation. It just seems to happen less ?
